Does anyone know a good plumber in the Runcorn area?

My hot water system seems to be kettling a lot and often heating the radiators when it should only be heating the hot water supply, which isn't great in the summer....
 
If the heating only gets hot when the system's calling for hot water it sounds like the heating supply valve is stuck open even though off or thermostat is turned down. If boiler runs all the time the stat is more likely the fault (call for heat = stuck on)

Might be worth a try before you spend out: Hoover out the crud and cobwebs from inside the valve motor casing, then a judicious few taps with a small hammer.
 
Three way motorised valve stuck by the sounds of it. If you have an siting cupboard you will find it in there with a lever which points to heating, water or centre for both.

A good place to start if your interesting in fixing yourself.

Now I'm home, it seems to be the one on the left, with the blue face thats the source of some of the noise, plus the tank itself sounding like a tap is running.

Ok, seems I'm learning stuff today.
For some reason I have two outputs to my radiator heating, each with a pump, is this normal?
But they then join into one just after the pumps, before separating again to go around the house. Maybe there were two loops that were later joined up. :-|

This noisy pump shouldn't be running as far as I know, as the central heating isn't set to on. Electrical issue?

Seems a plumber is needed, as I'm pretty limited when it comes to physical diy...
 
Looks odd, what's in that grey box above the two cross-lined pumps? Can't see any motorised valves, is there such a thing as a combined valve/pump?

Maybe it's working 'properly' as it is??? :rofl:

The two pumps must be controlled separately by the boiler, doing this negates the need for a motorised valve.

Might also be due to the size of the system :idunno:

two pumps in parallel is the norm on commercial systems, are theyu in parallel?

It seems that way, they're both wired into the same electrical box on the wall to the right but I haven't opened that up to see whats going on inside.

It's only a 3 bed semi detached house, nothing that I would have thought required excessive pumpage :?
 
Well, it's an interesting debate but not moving the OP any closer to a solution.. :rofl:
 
3 bed semi same as ours so doubt it is the size...

we have definitely had similar and it was the valve, but our system looks different to yours - we have one pump and two valves (three if you count the bypass valve controlled by the boiler for cooling). Looks like you have two pumps and no valves - so the pumps control the flow rather than valves.

but I'm no plumber :evil: :P

Can a pump stick on open :?

I just call British gas in when we have a problem as we have a service contract with them :oops:
